Honest about scope
We report what the cleaner actually handles. No claims we cannot stand behind.
How it works
Check first. Clean second.
Inspection and cleanup are deliberately separate steps, so you always see the evidence before anything is rewritten.
- 01
Paste copied text
Inspection runs in your browser. Nothing is sent anywhere and nothing is stored.
- 02
Read the exact result
Every marker is labelled with its Unicode code point, so there is nothing to guess at.
- 03
Clean it when you decide to
Use one of five free text cleanups, or unlock Pro for unlimited text cleanup and file processing.
What it finds
Every marker, named and coded.
The checker reports each character by its Unicode code point, so a result is something you can verify rather than trust.

Soft hyphens & separators
U+00AD · U+2028 · U+2029Break hints and separators that hide inside ordinary words.
Variation selectors
U+FE00–U+FE0F · U+E0100+Style modifiers often used to carry extra payload bits.

Questions
Before you use it.
What exactly does claudewatermarkremover find?
Invisible and default-ignorable Unicode characters: zero-width spaces, soft hyphens, direction controls, variation selectors, and tag characters. Line breaks are reported separately because they are normal layout characters, not hidden text.
Does the free checker change my text?
No. The checker is view-only: it inspects text locally in your browser and shows what it finds. Signed-in Free members can create up to five cleaned text outputs; Pro members have unlimited text cleanup.
Is my text uploaded anywhere?
Not in the free checker — it never leaves the page. Text cleanup runs in the workspace, while Pro file cleanup uploads only the file you choose. We keep metadata-only activity records for 30 days.
Can a clean result prove a document has no provenance signal?
No. claudewatermarkremover reports the supported characters and file metadata that its cleaner handles. It makes no claim about vendor-keyed or statistical provenance systems, and a clean report is not proof that one is absent.
